Objective Establishing UPLC multi-component content determination and fingerprint analysis methods for Yinchen (Artemisiae Scopariae Herba) from different sources. Determination the content, fingerprint analysis and chemical pattern analysis of Artemisiae Scopariae Herba (Mian Yinchen) and Artemisiae Scopariae Herba (Hua Yinchen) were conducted from 28 origins and 22 origins, respectively. Methods Using Waters ACQUITY UPLC BEH C18 (100 mm×2.1 mm, 1.7 µm) column as the stationary phase, 0.1% formic acid water (A)-acetonitrile (B) was used as the mobile phase for gradient elution, with a flow rate of 0.25 mL/min and a detection wavelength of 310 nm. The chromatographic peaks were confirmed by comparing with reference materials. A total of 50 different sources of Artemisiae Scopariae Herba were quantitatively determined for 14 compounds, and fingerprint analysis was performed to evaluate common peaks and similarity evaluation. Hierarchical cluster analysis and orthogonal partial least squares discrimination analysis (HCA and OPLS-DA) were used to screen the characteristic components of Artemisiae Scopariae Herba. Results Establishing a UPLC multi-component content determination and fingerprint method for Artemisiae Scopariae Herba; The quantitative analysis results indicated that there are differences in the chemical composition content of Artemisiae Scopariae Herba from different regions; The fingerprint method calibrated 18 and 32 common peaks for two harvesting periods, and chemical pattern analysis showed that 3,4-dicaffeoyl quinic acid, 3,5-dicaffeoyl quinic acid and 4,5-dicaffeoyl quinic acid can be used as landmark components for quality evaluation of medicinal materials. Conclusion The established UPLC multi-component content determination method and fingerprint method are suitable for quality evaluation of Artemisiae Scopariae Herba from different sources; The content determination results, fingerprint spectra, and chemical pattern analysis results from different origins can provide useful references for the selection of origin and quality control of Artemisiae Scopariae Herba.
